Justification:
This species is listed as Vulnerable as it has a small range, in which it is found at a limited number of locations, and its habitat is declining both in area and quality as a result of deforestation. Recent data, however, suggest that it may be present at more localities than previously thought. The taxonomic treatment of this species is under review and may change in the near future.

Robsonius rabori is found in northern Luzon, Philippines. It is considered uncommon, although tape playback indicates it may be widely overlooked (del Hoyo et al. 2007), and it has been described as fairly common around Adams in north-western Luzon and at Mt. Cagua in north-eastern Luzon (P. Hosner in litt. 2012). The population is thought to be declining owing to habitat destruction (del Hoyo et al. 2007, R. Hutchinson in litt. 2010).

The global population size has not been quantified, although it has been described as uncommon. However, it may be more common than suggested by field observations, owing to its secretive habits (del Hoyo et al. 2007).

This species is found in lowland forest and secondary growth from sea-level to 1,300 m. It presumably feeds on invertebrates, and has been observed walking across the forest floor searching for prey in the leaf litter, sometimes in pairs (del Hoyo et al. 2007, J. C. Gonzalez in litt. 2010). It is often encountered in the vicinity of small streams (D. Allen in litt. 2012). Very little is known about its breeding habitats. Its nest is a large dome made of dry sticks, branches and leaves (Sánchez-González et al. 2010).

Conservation Actions ProposedAssess the population size and establish a monitoring programme to establish trends. Establish its ability to persist in degraded habitats. Identify and assess threats. Ensure that the Northern Sierra Madre Natural Park is effectively protected
